Composite Cylinders

SCI SCBA

As one of the largest suppliers to the Self-Contained Breathing Apparatus industry (SCBA), SCI has been producing DOT approved composite cylinders since 1976 and has hundreds of cylinder models to select from.

SCI offers carbon, Kevlar and fiberglass wrapped SCBA cylinders with operating pressures up to 5000 psi. SCI's cylinders primarily use an aluminum liner except for Europe where regulations allow an all composite cylinder to be used. SCI can design a specific cylinder that will perfectly address a customer's needs of weight, length, diameter and operating pressure, or a customer can select from the hundreds of already approved designs.

SCI is always working to enhance our SCBA products with the newest technology available. Working together with our customers and their customers, SCI is able to provide the best solution to any SCBA need.

SCI Hall of Fame

SCI has provided cylinders for some of the most innovative and prestigious applications.

In 1972, SCI was the first composite cylinder manufacturer in the world to develop a high pressure cylinder for use in Fireman's Breathing Air System now known as a Self Contained Breathing Apparatus (SCBA).
